Say, did you ever read Java and wondered why you have to continuously
scroll to the right albeit using a 500-column terminal?

Exceedingly long names are fine to organise a large library, but becomes
burdensome when code only uses a subset of it... which is usually the

_both_ in reading and writing. The longer identifiers are, the shorter
information distance between two related ones tends to be, as in




compare this with locally-defined aliases 




Short notation isn't the problem, missing explanation of it is.[1]
Currently, you can observe stuff like

data Abst -- raction
    = Foo
    | Bar 

in my code. I don't mind making that a language feature for increased

Anyway, my code tends to get refactored more than being read or
written. I want to finish typing _before_ the next idea kicks in.
